Bharti Telecom, the parent company of Bharti Airtel, is planning its second bond sale in two months to raise approximately $1 billion (₹9,000 crore). The funds are primarily intended to refinance upcoming debt maturities, including ₹7,250 crore due in December. This move, supported by a recent AAA rating upgrade from CRISIL Ratings, aims to secure the cheapest borrowing costs for the company in four years, with mutual funds expected to be key investors.
